EE 2 has several possible causes. 1. Fuel problem 2. Dirty flame rod 3. Bad igniter 4. Circuit board If the fuel pump makes a loud ticking or thumping sound, you have a fuel problem. The pump makes this sound because no fuel is getting to it. This can be cause by a dirty filter at your tank, a dirty fuel strainer in the fuel sump, you are out of fuel, or have an air bubble in the fuel line. If the flame rod is dirty, the heater will light then go out after about a minute. If the igniter is bad the igniter will not light at all. You can test the igniter with an ohmmeter. The resistance reading should be around 17.2 ohms. I usually just use a clamp on ammeter and see if the igniter is drawing any amps when it is starting. If it is, it is good. You can check for voltage where the igniter connects to the circuit board. It should be 120vac. If not your circuit board could be bad. Let me know if you need a better explanation of anything. Hope this helps.
What is the best way to check for air in the fuel line? I recently moved my laser 73 and had to re-do the fuel line. I'm thinking I might have gotten air in the line. Also, how do you solve the dirty strainer in the fuel sump?What is the best way to check for air in the fuel line? I recently moved my laser 73 and had to re-do the fuel line.
